I've done a few reviews of Low Quality Posts. At one point I clicked "Looks Good", but it turned out someone (or the system?) disagreed. It may have been an honest mistake on my part, or perhaps I just disagree with the other person. However, my meta question is not about whether I was wrong or not.

This question is about whether the feedback I got can be improved. There are two things I noticed:

The next view I got explained that someone/something disagreed with me, and that I should review this discrepancy. However, the answer was deleted in the mean time, and I can't see deleted answers, so I couldn't reflect on my "mistake". See this screenshot:

When I tried to reload the page from my browser history, I got a similar screen, which had an additional confusing element: apparently the only review was mine? I had expected to see other reviewers that recommended deletion? See this screenshot:

That post had been flagged as spam outside of the review queue, and deleted long before you reviewed it. The answer in question (10k+ only) was deleted by a moderator, shortly after it was posted:

It probably should not have been shown in the queue in the first place. A bug, in other words.

However, if it was placed in the queue intentionally (in order to teach reviewers about what spam can look like), then you've found a bug in that it should've shown you what the post looks like when you were admonished for not having recommended deletion.

Thanks, this was the info I was after. I did make a review mistake then :O tsk tsk. Would be good to hear from those who know whether this should've been in the queue or not, and if so whether we this situation could show a one-time peek at the deleted answer, for educational purposes.

This is actually by design: the answer you saw was a previously deleted spam answer that was inserted into the review queue as an automated test of your reviewing accuracy.

What is clearly a bug, however, is that you couldn't see the answer on the "test failed" page. You should either edit your question to focus on that aspect, or post a separate question about it (with the tags bug and review-audits).
